Next, connect the following pins from the ST-Link/v2 to the pyboard. Refer to the [ST-Link/v2 User Manual](https://www.st.com/resource/en/user_manual/dm00026748.pdf).
```
ST-Link/V2 | pyboard v1.1
----------------- | -------------
PIN1 (VAPP) -> 3V3
PIN7 (TMS_SWDIO) -> PA13 (X21-2)
PIN9 (TCK_SWCLK) -> PA14 (X20-2)
PIN13 (TDO_SWO) -> PB3 (X17-1) (Optional debug serial)
PIN15 (NRST) -> RST
PIN20 (GND) -> GND
```
# Programming
You can now program/debug using any software that support the ST-Link/v2. One such program is [OpenOCD](http://openocd.org/).
```bash
$ openocd -f board/stm32f4discovery.cfg -c "program app.elf" -c reset -c shutdown
```
Debugging has been tested to work under CLion.
